Bacterial Colonosis' in Patients with Persistent Fatigue

'Bacterial Colonosis' (BC) in patients with persistent fatigue is a disease entity that has not been described in medical literature. Patients with this condition usually present with multiple disorders including gastrointestinal symptoms, characterized by an absence of gastrointestinal inflammation and a marked alteration of intestinal microbial flora. This condition of unknown aetiology is manifested in patients with Chronic Fatigue Syndrome (CFS), Fibromyalgia, Irritable Bowel Syndrome, and Autism. In a study of 1390 fatigued patients, fatigue presentation in patients with BC was more severe than patients without BC (p<0.015). Similarly muscular pain (face, neck, shoulder and lower back) in fatigued patients with BC was significantly more severe (p<0.01) than patients with minimal or no BC. The distribution of faecal intestinal microbial flora in this study population was markedly altered. The mean % distribution for the organism Escherichia coli was 36.6% of the total aerobic flora, a count significantly lower (p<0.001) than those found in healthy subjects (70-95%). By contrast the lactic acid bacteria Enterococcus spp was significantly higher (p<0.001, 28.7% of the total aerobic flora in fatigued patients ) than with the healthy subjects (3-5%). Patients with chronic fatigue also had marked decrease in Bifidobacterium spp. count (<0.35% of the total anaerobic flora). Changes in the gastrointestinal microbial ecology are significantly associated with fatigue symptoms. A high faecal enterococcal count significantly and positively correlates with neurological and cognitive functions (nervousness (p<0.05), memory loss (p<0.01), forgetfulness (p<0.01), confusion (p<0.05), mind going blank (p<0.01)). Similarly a high aerobe/anaerobe ratio significantly and positively correlates with poor colonic functions, poor digestion, and malabsorption of the gastrointestinal tract.
